Operating Instructions
Read mV / V
Choose this function to measure from -99.999 to 99.999 millivolts, -999.99 to
+999.99 mV, 0.000 to 10.250 V dc or 0.00 to 60.00 V dc.
Move the power switch to READ then Double Click the EZ-DIAL knob to get into
the Menu. Turn the knob to scroll through the settings and press the knob to
make your selection. Select V for the FUNCTION and 1V, 10V, 60V or 100 mV
for the RANGE.
Connect the red input lead (+) of the 830PM to the more positive point of the
break and the black input to the more negative point. When measuring up to 100
mV connect the red lead to jack (1) and the black lead to jack (2). When
measuring up to 1V, 10 V or 60 V connect the red lead to jack (5) and the black
lead to jack (6).
Signals above the maximum scale are limited by protection circuitry with “OVER
RANGE” on the display and the red OVERLOAD LED lit.
The 830PM measures the input signal and constantly updates the display with
the current reading. Move the EZ-CHECK switch
q
to MAX to see the highest
reading and to MIN to see the lowest reading. Press and hold the knob
e
to clear
the MAX and MIN readings.
